Abstract: The invention relates to a method of selection of an ophthalmic lens suitable for correcting at least an optical impairment of an eye of a wearer who observes a screen. According to the invention the method comprises the steps of: determining at least a characteristic of posture of the wearer observing said screen, determining a dioptric power value associated to said vision zone allowing the wearer when wearing the ophthalmic lens to have an easier reading of said screen, determining at least one characteristic of filtering means to adjust the light exposure of the wearer to said screen, and determining the vision zone based on dioptric power value, characteristic of posture of the wearer and characteristic of filtering means so that the vision comfort of the wearer is optimized when wearing the ophthalmic lens while observing a screen.

Abstract: The invention relates to a method of selection of an ophthalmic lens suitable for correcting at least an optical impairment of an eye of a wearer who observes a screen.

Abstract: A method of preparing an ophthalmic lens (20) for mounting in an eyeglass frame, the ophthalmic lens including a memory mark (28) that is situated on one of its ophthalmic faces (22) and that forms a code storing in digital form at least one item of information relating to a mechanical, geometrical, or optical characteristic of the ophthalmic lens. The method includes three steps: a) acquiring a raw image of at least a portion of the optical face of the ophthalmic lens on which an image of the memory mark appears; b) processing the raw image acquired in step a) in order to decode the information stored in the code; and c) centering and then shaping the ophthalmic lens as a function of the information decoded in step b).
